Montville — A man who is in state Department of Correction custody on charges including attempted murder was arrested again Friday for allegedly assaulting a Corrigan Correctional Institution employee, according to state police.

Jachim Lamar Brown, 27, was charged with first-degree assault on a DOC employee. The charge is a Class B felony that generally only is seen when a weapon is used and/or there’s intent to cause serious injury.

According to police, Brown attacked the officer about 9:45 a.m. Friday. Crews had to transport the officer to The William W. Backus Hospital for treatment of unspecified injuries.

Brown, who has been transferred to the Northern Correctional Institution in Somers, is due to be arraigned on his latest charges March 29 in Norwich Superior Court. Northern Correctional is a level five, maximum security facility.

Court records show he has a host of other pending cases, with charges primarily out of Bridgeport and Stratford that include but aren’t limited to attempted murder, first-degree robbery and first-degree assault with a firearm.

According to the Hartford Courant, the attempted murder charge stems from a November incident in which Brown, suspected in a Bridgeport clothing store robbery, allegedly shot at an officer as he was running from the scene of the crime.
